Flying Justice: Transportation of Prisoners by U.S. Marshals

The Justice Prisoner and Alien Transportation System (JPATS) of the United States Marshals manages the coordination, scheduling, and secure handling of federal prisoners, transporting them to detention facilities, courts, and correctional institutions via a network of aircraft, buses, vans, and cars.
JPATS is the nation's largest prisoner transporter, serving the federal judiciary, U.S. Marshals district offices, and the Federal Bureau of Prisons. JPATS is the country's only government-operated, regularly scheduled passenger airline.
It transports prisoners through more than 40 airlift sites across the United States and its territories.
JPATS air operations are carried out using JPATS-owned and leased aircraft, which are piloted by specially trained aviation security personnel, expert pilots, medical personnel, and experienced mechanics.
JPATS operates a fleet of aircraft to transport prisoners.
